Book excerpt: Transpathology: Molecular Imaging-Based Pathology is a multidisciplinary reference on molecular imaging and pathology. The book is intended for professionals in the fields of molecular imaging, nuclear medicine, radiology, and pathology as well as students and clinical residents. The book describes the importance of non-invasive diagnosis-based precision medicine and presents a detailed description of current transpathological approaches in different aspects essential for the future development of precision medicine. It's molecular imaging approach to experimental research and clinical practice will drive the field forward and improve research outcomes. - Introduces a new concept of molecular imaging-guided precise biopsy - Links in vivo and ex vivo information at various scales by using multi-modality imaging technologies - Integrates future technologies for the non-invasive cross-validation of underlying mechanisms
